Oldest Charities and Organizations That Help Endangered Animals

Without wildlife, life as we know it wouldn't exist. We wouldn't exist. It's all too easy to get so swept up in our busy lives that we forget we're animals, too, reliant on our planet's natural resources to survive. Everything in our world is connected. Helping endangered animals survive isn't just for them. It's also for us, ensuring that planet Earth remains a beautiful oasis of living things for future generations of humans and other animals alike.

Most threats to biodiversity are human-made. It's our responsibility to repair what we broke from the ground up. Dozens of organizations dedicate their work to wildlife conservation, but these 10 animal charities are among the oldest and top-rated.
